SYNOPSIS : Calendar Manager "Most Frequently Asked Questions" list
DETAIL DESCRIPTION :
Calendar Manager -- Most Frequently Asked Questions
1. Where does calendar manager store its data?
2. What should the ownership and permissions be for the /usr/spool/calendar
directory and the callog files found there?
3. What other files are related to Calendar Manager?
4. How can Calendar Manager information be moved to another system?
5. Is it possible to share/NFS mount the /usr/spool/calendar directory?

9. What might be the cause of the message "rpc.cmsd file error on
/usr/spool/calendar/callog.$USER"?
Q1: Where does calendar manager store its data?
A1: Calendar manager appointment information is stored in the
/usr/spool/calendar directory in the callog.$USER file.
Q2: What should the ownership and permissions be for the /usr/spool/calendar
directory and the callog files found there?
A2: % ls -alg /usr/spool
drwxrwsrwt 2 daemon daemon 512 Aug 27 03:59 calendar/
The 's' bit is the setuid bit used to set the group id to
daemon. The 't' bit is the sticky bit which only allows
the owner to remove files into /usr/spool/calendar.
To set these proper permissions, use the following commands as root:
# chown daemon.daemon /usr/spool/calendar
# chmod 1777 /usr/spool/calendar
# chmod g+s /usr/spool/calendar
% ls -alg /usr/spool/calendar
drwxrwsrwt 2 daemon daemon 512 Aug 27 03:59 ./
drwxr-sr-x 19 bin bin 512 Aug 26 09:44 ../
-r--rw---- 1 user1 daemon 19147 Aug 26 04:20 .calbak.user1
-rw-rw---- 1 daemon daemon 0 May 9 15:33 .lock
-r--rw---- 1 user1 daemon 19147 Aug 27 03:59 callog.user1
The callog file is owned by the user and MUST HAVE 460 permissions.
To set the proper permissions on the callog file, use the following
commands as user1:
% chmod 460 callog.user1
If these exact permissions are not maintained on both the
directory and the files, the software suspects an intruder
and refuses access to the data.
Q3: What other files are related to Calendar Manager?
A3: o $OPENWINHOME/bin/xview/install_cmgr (in SunOS 4.1.X only):
install script for setting up the calendar manager
and adding rpc.cmsd to the inetd.conf file
o $OPENWINHOME/bin/xview/rpc.cmsd:
calendar manager services daemon which manages all calendar
data. There is one rpc.cmsd daemon process per host.
o /etc/inetd.conf:
modified via the install_cmgr script to contain rpc.cmsd.
In this way, rpc.cmsd is started automatically by inetd.
o /usr/spool/calendar:
directory containing calendar data files
o /usr/spool/calendar/callog.$USER:
file containing $USER's appointments
o /usr/spool/calendar/.calbak.$USER:
backup copy of the callog.$USER file, created each night
after garbage collection
o /usr/spool/calendar/.lock:
zero-length file used for mutual exclusion
o $HOME/.cm.rc:
resources file, modified when calendar manager properties
are applied
Q4: How can Calendar Manager information be moved to another system?
A4: The information for a user's calendar resides in the file
/usr/spool/calendar/callog.$USER. Before moving the file,
check to make sure that no one is using that calendar on the
new system. Then copy the callog.$USER file to the new
system's /usr/spool/calendar directory, and do the following
commands as root:
e.g., if the callog file belongs to user "user1",
# chown user1.daemon callog.user1
# chmod 460 callog.user1
Finally, before the appointments will appear, the following must be
done as root:
# setenv OPENWINHOME /usr/openwin
# $OPENWINHOME/bin/xview/install_cmgr
o quit all Calendar Managers
o kill the rpc.cmsd daemon (check with ps -aux | grep rpc.cmsd)
o restart Calendar Manager
Q5: Is it possible to share/NFS mount the /usr/spool/calendar directory?
A5: NFS mounting of the /usr/spool/calendar directory across machines is
not a supported configuration in OpenWindows 3.0, 3.0.1, and
3.1. However, support for centralized calendar data is
expected for the version of OpenWindows bundled with Solaris 2.2.
Workarounds for OpenWindows 3.0, 3.0.1, & 3.1 are available as follows:
o Use the following script as a replacement of /usr/openwin/bin/cm on
the client machines so as to run the cm process remotely and
display it on your local system.
#!/bin/csh
$OPENWINHOME/bin/xhost servername
rsh servername "setenv OPENWINHOME /usr/openwin; \
setenv LD_LIBRARY_PATH $OPENWINHOME/lib; \
$OPENWINHOME/bin/xview/cm -display `hostname`:0 $* &" &
Please replace "servername" with your server's hostname.
o Centralize your calendar callog files on machine "servername",
then on your client machines, modify your $HOME/.cm.rc file's
"Calendar.DefaultCal:" entry to $USER@servername. Then from
servername, bring up Calendar Manager and give Browse, Insert,
and Delete permission to each client machine that will be
accessing the calendar from the calendar server. This can be
achieved under the Edit->Properties->Access List and Permissions
window.
Q6: cm_insert doesn't seem to work as documented, is a patch available?
A6: Yes! Please call 1-800-USA-4SUN to order the Calendar Manager
Jumbo Patch, 100523.
Q7: When choosing a day, why does the previous day get selected?
(Or why are all appointments off by x number of hours?)
A7: This is because the kernel timezone is set to GMT. To remedy this,
run "tzsetup", located in /usr/etc, as superuser.
Q8: Why does the message "rpc.cmsd not responding, Have you run install_cmgr?"
come from Calendar Manager, even after running the install_cmgr script?
A8: Calendar Manager doesn't function without rpc.cmsd, the Calendar Manager
database daemon. If you get the error messages above, rpc.cmsd is
likely not running or it has somehow lost its connection to the inetd
daemon (the process which initiates rpc.cmsd).
This symptom can be caused by one of the following problems:
o Calendar Manager used to work prior to changing the hostname.
Solution: Make sure all the necessary files in /etc
(e.g., hosts, ethers, hostname.*, hostname.le0, hostname.le1,
exports, xtab) are updated to reflect the hostname change.
o Calendar Manager can fail on a standalone machine if the
loopback network is not correctly set up.
Solution:
Step 1: Edit the /etc/hosts file and merge into a single line the entry
for your machine's hostname and the entry for "localhost", for example:
127.0.0.1 hostname localhost loghost mailhost
Step 2: Edit the /etc/rc.boot file and comment out all the
ifconfig commands by adding # at the beginning of each line,
for example:
#if [ ... ]; then
# ifconfig
#fi
Step 3: Reboot machine
o Any changes made to the /etc/inetd.conf file must be followed by the
following steps for reinitiating the Calendar Manager:
Solution:
Step 1: Edit the /etc/inetd.conf file and delete the following
line, and duplicates if any:
100068/2-3 dgram rpc/udp wait root /usr/openwin/bin/rpc.cmsd rpc.cmsd
Step 2: Use "ps aux | grep rpc.cmsd" to see if rpc.cmsd is running.
If it is, issue "kill -9 <rpc.cmsd process id>".
Step 3: Use "rpcinfo -u <hostname> 100068" to view the port status,
which should look like this:
program 100068 version 2 ready and waiting
program 100068 version 3 ready and waiting
program 100068 version 4 ready and waiting <- only on Solaris 2.2
Step 4: Rerun install_cmgr "$OPENWINHOME/bin/xview/install_cmgr"
Step 5: Restart Calendar Manager.
Q9: What might be the cause of the message "rpc.cmsd file error on
/usr/spool/calendar/callog.$USER"?
A9: The $USER account is no longer available. However, other users' Calendar
Managers are still attempting to access the $USER in their multi-browser
list entry as $USER@machine. Perform the following steps for each of
the users experiencing the problem:
Step 1: Edit the file "$HOME/.cm.rc" and remove the reference to
"$USER@machine" under "Calendar.CalendarList:"
Step 2: Use "ps aux | grep rpc.cmsd" to see if rpc.cmsd is running.
If it is, issue "kill -9 <rpc.cmsd process id>".
Step 3: Restart Calendar Manager to flush the registration list
